This application claims the benefit of priority afforded by provisional application Ser. No. 60/588,394 filed Jul. 16, 2004.
The present invention relates to data synchronization agents for use in computer systems.
Modern computer users often find that they are required to store copies of redundant data on multiple clients. For example, an operator may maintain personal scheduling information, contacts and lists of action items on both a desktop computer and a portable personal digital assistant. Moreover, operators may maintain such data on personal information managers (e.g., Microsoft's Outlook, Lotus Notes, among others) and also centralized enterprise resource planning applications such as SAP's R/3 application. To relieve operators from having to enter common data records multiple times for multiple applications (herein, “clients”), synchronization agents can be used.
Herein, a “synchronization agent” refers to a body of applications that synchronize data records among multiple clients. PalmSource, Inc.'s HotSync application and PumaTech Corporation's Intellisync suite of applications are examples of such synchronization agents. Known synchronization agents adequately synchronize data records among a pair of clients but they are unwieldy in many aspects. Known synchronization agents tend to provide a single synchronization solution for all users or to permit operators to specify different synchronization rules on a very coarse scale (e.g., calendar items synchronized in one fashion and contacts items specified in another fashion). They do not, however, permit operators to customize operation of the synchronization agent along parameters that are critical to the operators' use of the data records. For example, known synchronization agents do not permit operators to:
As described herein, the inventors propose a suite of synchronization features for use by a synchronization agent. Some of the embodiments enhance conventional synchronization features by providing customizable response of a synchronization agent to an operator's needs. For example, different synchronization operations may be defined based upon the content of data records themselves, by records' time of creation or editing or by records' status.
The system 100 also includes a synchronization agent 130, an application that manages synchronization of data records between the clients 110, 120. Typically, each client 110, 120 includes an appropriate interface 116, 126 through which the client recognizes synchronization operations from the synchronization agent 130. When activated, the synchronization agent 130 reviews records from various data sets 114, 124 of the clients to determine whether the data records on each client should be copied to the other client to keep them current. In this regard, the architecture and operation of synchronization systems 100 is well known.
According to an embodiment of the present invention, a synchronization agent 130 applies different synchronization rules to different records stored in the datasets 114, 124 of the clients 110, 120. In such an embodiment, synchronization options are determined from fields of the data records themselves. For example, different synchronization options may be applied based on a company name, a billing code, a project code or a categories field provided within such records. Synchronization options would be defined in a synchronization rule set 132 defined for the synchronization agent 130.
Company Name =
Client 110 records overwrite client 120
records; Flag conflicts for resolution.
Company Name =
Client 120 records overwrite client 110
records, regardless of conflicts.
Client 110 records cannot be overwritten.
Conflicts with client 120 records cause
duplicates to be created at client 110.
Do not synchronize records.
Synchronize; flag conflicts for resolution.
Table 1 illustrates an exemplary synchronization rule set with four rules. In this embodiment, two rules are conditioned on company name. The third and fourth rules are based on a field called “category.” Different synchronization policies are defined therein. Any data records that matches the condition(s) specified in a rule will be synchronized as defined in the corresponding synchronization policy. Data records that miss conditions of all rules may be synchronized according to a default rule. In an embodiment, data records that match conditions of multiple rules may be flagged to a system operator for resolution. Alternatively, the rules may include a priority indicator that specifies which rules take precedence over other rules.
As noted, various fields in client datasets 114, 124 may support rule conditions. Typically, conditions will be based on client names, client codes, project codes, matter numbers, account owners and status indicators such as open/closed indicators. Such examples are not meant to be limiting. Indeed, any field supported by the Microsoft Outlook field template may be included as a condition in a rule set.
Table 1, of course, provides a simple example of a rule set. The present invention includes more complicated definitions of conditions and accommodates, for example, common Boolean operators (AND, OR, NOT) to build conditions from combinations of multiple fields.
Another embodiment provides a technique for managing conflicts among data records stored by multiple clients 110, 120. According to an embodiment, when a synchronization conflict occurs, data representing conflicting data records are displayed and an operator is permitted to identify which fields from the data records are to be retained for synchronization.

Another embodiment of the present invention provides a “synchronize this” feature for a client application. In the embodiment, as an operator browses through data records of a client application, the operator may generate a command to synchronize a single data record currently being viewed. This embodiment prevents the synchronizing agent from having to survey all data records in a dataset to determine which records need to be synchronized. Accordingly, the speed of the synchronization operation is improved.
In an embodiment, the synchronize this command may be entered via an icon embedded in the client application. Many applications, such as Microsoft Outlook for example, provide software tools to permit other software vendors to embed icons in the graphical user interfaces of their applications. Thus, the command may be entered via a toolbar or icon set that is integrated into the client application itself (e.g., Microsoft Outlook, SAP R/3) or, alternatively, it may be entered through the client's operation system. In either case, the command causes an application to determine which record is being viewed currently and synchronizes the record itself.
Operation of the foregoing method may be facilitated by a synchronization agent 660 that stores rule sets 670, 680 for each of the clients subject to synchronization. The rule sets 670, 680 may specify, for example, that records are to be copied to the client, may not be copied to the client or shall be copied to the client only if defined conditions are met.
Of course, the operations of boxes 730-760 need not be performed for a data record that is identified as complete. Instead, synchronization may be performed directly upon a complete data record (box 780).
In an embodiment, the preview pane of
According to the embodiment, when a synchronization command is entered, the method 1100 may authenticate the local client (box 1110) to determine which client is engaged with the central client. Thereafter, the method 1100 may retrieve a synchronization rule set that is specific to the local client (box 1120). The method 1100 continues by synchronizing data records (e.g., calendar items, tasks and contacts) as determined by the synchronization rules (boxes 1130-1150). For each data records, the method 1100 determines whether synchronization of the record would cause write-protected records at the central client to be over-written (box 1160). If so, the record is not synchronized (box 1170). This scheme prevents protected data records at the central client, which perhaps could be amended at one or more local client sites, from becoming corrupted.
In another embodiment, the present invention may use links established among records of a first client to automatically populate data of corresponding records at a second client. This embodiment finds application, for example, in SAP's Customer Relationship Management (“CRM”) applications and elsewhere, where all records are required to be associated with a business partner. That is, records include a business partner field that is a “critical field,” it must be completed for the record to be admitted to the application. In some installations, however, new records may be admitted to other clients (e.g., a personal information manager) that either do not support the critical field or do not require that the critical field be completed before the record is admitted to the other client. Synchronization between the two clients, the CRM application and the personal information manager, may cause a conflict in data management policies.
According to an embodiment, a synchronization agent may resolve a conflict by examining links established between records of a client and populating missing critical field data in a new record by using corresponding data from a previously admitted record.
In additional to population of critical field data of records, a synchronization agent may populate other record fields by traversing these links as well. Accordingly, if the synchronization agent determined that an address field or a company name field were incomplete, the synchronization agent could copy such information from a linked record. Of course, in all of the foregoing embodiments, the synchronization agent may query an operator to confirm copied data prior to completing the synchronization operation.
Another embodiment of the present invention provides support for CRM applications by supporting synchronization of customer “snapshots” from a CRM application to a second client.
The CRM client 1410 may include an application component 1412 and a database 1414 that stores customer related data. In addition to records representing activities, contacts, appointments and tasks as described above, conventional CRM applications store records representing customer sales, quotations, customer accounts and the like.
The synchronization agent 1430 may store a data set representing report templates that may be used for synchronization. Each template corresponds to a predetermined “snapshot,” a summary report identifying status along a selected CRM dimension. Operators may selectively enable various templates for each client and may enable different sets of templates for different customers. During synchronization, a synchronization agent may engage the CRM client to collect summary data as dictated by the selected template and create snapshot files on the second client. For example, each template may be represented on a separate sheet of a spreadsheet file on the second client, each file representing a snapshot of an individual customer. Through use of the snapshot feature, an operator may generate summary data records from a CRM application that are amenable to mobile applications, among others.
Functionality of the foregoing embodiments may be provided on various computer platforms executing program instructions. Commonly, such computing platforms include one or more processors, a memory system and various input/output (I/O) devices. The processor may be any of a plurality of conventional processing systems, including microprocessors, digital signal processors and field programmable logic arrays. In some applications, it may be advantageous to provide multiple processors (not shown) in the platform. The processor(s) execute program instructions stored in the memory system. The memory system may include any combination of conventional memory circuits, including electrical, magnetic or optical memory systems. For example, the memory system may include read only memories, random access memories and bulk storage. The memory system not only stores the program instructions representing the various methods described herein but also can store the data items on which these methods operate. The I/O devices permit communication with external devices (not shown) and operators.
